Abstract
The present invention addresses the problem of providing: a porous carbon structure that has a high micropore volume and can be self-contained; a manufacturing method therefor; a positive electrode material using the same; and a battery (particularly an air battery) using the same. The present invention is a porous carbon structure that is for a positive electrode for an air battery and has voids and a skeleton formed by incorporating carbon, the porous carbon structure satisfying all of the following conditions (a) to (d). (a) The t-plot external specific surface area is within the range of 300 m/g to 1600 m/g; (b) the total volume of micropores having a diameter of 1 nm to 200 nm is within the range of 1.2 cm/g to 7.0 cm/g; (c) the total volume of micropores having a diameter of 1 nm to 1000 nm is within the range of 2.3 cm3/g to 10.0 cm/g; and (d) the overall porosity is within the range of 80% to 99%.
